    The parts should be in stock , the coil is reasonably priced but the armature kit if needed is quite pricey (part of the valve the coil sits over), but still a lot cheaper than a complete new valve assembly. Jase.

    As mentioned, it could be the solenoid valve or the bottom coil on the valve for infeed ? This valve is mounted by the indexing lever for the turntable , it has two coils , both with a square Herschmann plug connected to them. I would suggest undoing the screw that holds each plug on and swapping the plugs over then run the chipper at maximum revs , press the palm switch and see if , by doing this the rollers will feed in reverse ? If so then I would suspect that the bottom coil is faulty. You can confirm this by pulling the red bar for reverse to see if the rollers will now feed forwards ? If they don't instantly work then this would confirm a coil failure. Jase.

    Any update on this yet ?

    Yes , it's off the end of the moving roller carriage , usually held in place with two 8mm bolts..
  6. Jase hutch
    Did it previously run ok before ?

    Hi Soeren, It's normally tight and usually requires a puller although you may be lucky with a large hammer and soft drift to avoid damaging the feedroller shaft. Jase.

    That's an exception..😂

    Basically when new , the blades are 100mm in diameter and can be ground down until the diameter is 90mm. If you look at the large face of a new disc blade you will see a 5mm ring around the circumference , when this is no longer visible the blades are at the end of their life.

    Yes he's gonna be missed by me.

    It is indeed flywheel speed that's shown on the display and the A150 should run at 1850.

    Mick , that angled piece that's broken off simply fills in the gap to the side of the roller and helps to guide in the material. It shouldn't effect the operation of the chipper. It's simple enough to replace the broken mounting bracket though . Jase.

    You are welcome to give me a call on: 01789400044 and option for service... Jase.

    It sounds like it could be the PCB board in the ignition box but we are showing as 'none in stock' ! Where are you based ? Jase....
  15. Jase hutch
    Hi Keith , So if you turn the ignition on with the bonnet shut and override button pressed, does the fuel pump tick ? Jase.
  16. Jase hutch
    Or it's on top by the air filter.. It's the 20amp fuse and it's connections that need checking.. If that appears OK it may be a fuel blockage ? When was the fuel filter last changed ? Jase.

    They leave the factory with 32 grade but 46 is fine. Where's the oil leaked from ?
  18. Jase hutch
    bib is the manufacturer and it's cast into the block. The size of thread and the length from the shoulder above the 'o' ring to the point with it wound fully in should be enough Chris and then I'll compare it to one at work tomorrow..
  19. Jase hutch
    It looks like a simple flow control valve. Can you add dimensions to a photo ? Is the control valve a 'bib' valve ? I think we have the same in stock at GreenMech...

    Mick , is the spring on the moving roller tight enough ? Does it snap back if you try to pull the carriage across by hand or does it feel elastic ?
  21. Jase hutch
    That's the display Mick , you need to take the lid off the 'junction box 'which is next to the battery..
  22. Jase hutch
    No the RDS junction box is mounted above the battery on top of the infeed chute. Unscrew the four screws and remove the lid and if you look at the circuit board there's a small blue potentiometer in the centre of the board that's adjustable using a small screwdriver. Turn it clockwise to increase the kickback and anti clockwise yo decrease it , it's very sensitive. Also it's best done when the hyd oil is warm..

    I would say that if you have a rev counter and can check the actual rpm of the shaft in question, be it engine or flywheel shaft speed , then guess at a pulses figure to input and try it to see what speed is displayed ? For example an alternator on a Greenmech 19-28 mk1 has a pulses per rev of 20.9 if I remember rightly. By doing this if you know the actual speed using a rev counter then just keep trying inputting different pulse settings until the display shows the correct speed.

    Any joy with this ?

    If the No-Stress light works as stated , do the feedrollers infeed even at tick over ? If so then the first thing to check is the position of the override tap ? This is mounted on the back of the chipper chamber next to the No-Stress solenoid valve , the lever on the tap should be in line with the fittings on the valve. If the tap is turned by ninety degrees the feedrollers will infeed regardless on engine rpm. If the tap is in the correct position then check at the nut that holds the coil onto the solenoid valve , there should be magnetism there only when the NS light is green. If this checks out correctly but you still have infeed on tick over then I would suspect a sticking solenoid valve. Jase
